简介
Extreme cold events frequently occur around the world in recent several years and arouse widespread concern. In this study, 17 record-breaking event processes (RBEPs) of low temperature during 1981–2012 are identified by using daily minimum temperature at 1897 meteorological stations in China. These RBEPs are classified into two types based on the occurring area at northern or southern China to compositely examine the associated circulations. Although the correspondence between Arctic oscillation (AO) and RBEPs is not linearly stable, there still exist relationship between them, i.e. under AO negative phase the RBEPs tend to occur at northern China, nor the southern part, where the RBEPs prefer to happen under AO positive phase. In the RBEPs occurring at southern China, the continent high pressure over Mongolia area is extremely intensified and the East Asian polar front jet stream is …
